Lenovo Yoga L390 11.1V Replacement Battery 01AV482

Up to 17% off
New arrival
From $97.99 USD $117.99
Shipping calculated at checkout.
Fits Lenovo Yoga L390, ThinkPad L380, and ThinkPad S2 Yoga 2018 — replaces OEM part 01AV482.
11.1V, 3950mAh lithium-polymer cell delivers 43.85Wh to restore full charge cycles on this ultrabook platform.
Connector seats flush into the battery bay slot with a single locking tab — no adapter needed.
We bench-tested this cell through five full discharge cycles; the BMS reported stable voltage throughout the charge plateau.
After installation, run one complete discharge to sleep mode, then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears health warnings that appear after cell swaps.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Lenovo Yoga L390 / ThinkPad L380 — 11.1V Li-Polymer Replacement Battery (01AV482)

This 11.1V, 3950mAh (43.85Wh) lithium-polymer cell replaces the original battery in the Lenovo Yoga L390, ThinkPad L380, ThinkPad S2 Yoga 2018, and the ThinkPad Yoga L380-20M7001BGE, among over 220 additional variants. It fits the same physical bay and uses the same multi-pin connector as the OEM unit. Part numbers 01AV482, L17M3P55, and SB10K97626 are all covered by this cell.

  • L380 and L390 platform fit: These models share a common battery bay geometry, connector pinout, and BMS handshake protocol across the L380 and L390 board revisions. The BIOS reads the same EEPROM data structure regardless of which board variant you're running, so the cell seats and registers without modification.
  • Bench tested on actual hardware: We cycled this cell on a ThinkPad L380 unit, monitoring charge acceptance and BMS communication at each stage. The protection circuit handled full charge termination and low-voltage cutoff cleanly, with no dropped connections across the data pins during discharge.
  • Post-install calibration on the L380/L390: After fitting this cell, run the laptop down to hibernate-cutoff on battery alone — no sleep, screen on — then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting poor battery health immediately after fitting a new cell

The ThinkPad BIOS stores charge history and health metrics in the old cell's EEPROM. When a new cell goes in, that data is gone, and the firmware flags the battery as degraded because it has no cycle history to read. This is not a fault with the replacement cell — it is the BIOS reacting to a blank slate. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% gives the firmware enough data to rebuild its health estimate. After two or three full cycles the reported health figure will normalise.

Laptop shutting down at 20–30% shown on the fuel gauge

The fuel gauge IC calibrates against the old cell's voltage curve, not the new one. When the L380 or L390 hits a load spike — CPU burst plus display at full brightness — cell voltage drops faster than the gauge expects, and the system interprets it as a hard low-voltage event and shuts off. The displayed percentage at cutoff is wrong; the cell is hitting its actual voltage floor earlier than the gauge predicts. Force two full discharge cycles to hibernate-cutoff to let the gauge IC map the new cell's curve. After calibration, shutdowns should not occur above approximately 3.2V per cell under normal load.

Frequently Asked Questions

Why does Windows show the Yoga L390 battery as 0% or "unknown" right after I put the new one in?

The fuel gauge IC in the L380/L390 reads state-of-charge from EEPROM data written by the old cell. A new cell ships with a blank or factory-default EEPROM, so the IC has no reference point and reports 0% or an unknown state. This is not a fault with the cell. Charge to 100% uninterrupted, then discharge fully to hibernate-cutoff — one complete cycle is usually enough for the IC to lock onto the new cell's voltage curve and report accurately.

The ThinkPad L380 BIOS shows the wrong Wh rating after I swapped the battery — it says 45Wh instead of 43Wh. Is the cell incorrect?

The Wh figure the BIOS displays is read from the cell's EEPROM, which stores the rated design capacity written at the factory — not the measured capacity of the specific cell you received. A small difference between the EEPROM-declared value and the actual 43.85Wh spec of this cell is normal and does not affect charging or discharge behaviour. The BIOS will not recalculate this figure; it reads the stored value every time. No action is needed — the cell is operating correctly.

My replacement L390 battery charges to about 80% then stops — is something wrong with the cell?

Most likely not. Lenovo BIOS on the L380 and L390 series includes a Conservation Mode setting that caps charge at 80% to reduce long-term cell stress. Check Lenovo Vantage under Power — if Conservation Mode is enabled, the 80% cutoff is a firmware instruction to the charger, not a cell fault. Disable Conservation Mode and the battery will charge to 100%. If Vantage is not installed, toggle the setting in BIOS under Config → Power → Battery Charge Threshold.
